Bouncer Validates Emails.1Lookup Validates Everything.
Bouncer covers email verification well, but only email. 1Lookup delivers multi-service validation from one credit balance. As the leading Bouncer alternative, we offer phone + email + IP validation in one platform with a fraud score on every lookup.
Two ways to keep contact data clean
Bouncer focuses on email verification. 1Lookup verifies email, phone, and IP from one API and one credit balance.
The 1Lookup approach
- Real-time email checks: syntax, domain, MX, SMTP, catch-all, disposable, and role-based
- A deliverability read and a fraud score on every address
- The same API key also validates phone numbers and IP addresses
- One real-time endpoint plus bulk list cleaning, drawn from one credit balance
- Data checked in real time, identical lookups cached for 7 days
- Live in about 5 minutes, with 1,000 requests/min included
The Bouncer approach
- Focused email verification and list cleaning
- Real-time API plus bulk file uploads
- Well-regarded deliverability accuracy
- Email-only: phone and IP are not part of the product
- Priced as a standalone email tool
If all you need is email verification, Bouncer does it well. If you also want phone and IP validation with fraud scoring on the same key, that is where 1Lookup fits.
Good tool, no fluff
Been using 1Lookup for a couple months now. We verify leads before pushing them into Pipedrive. Honestly it just works. Not fancy, not buggy, and the support actually answers when you write them. Can't really ask for more.
Brian LetzterUnited States · October 2025The most practical data tool I've used
I've seen hundreds of validation APIs come and go. 1Lookup stands out because they don't oversell. Their data is solid, support is honest, and they're transparent about limitations, which is rare in this industry. I've replaced three tools with this one. They listen, they iterate, and they keep improving. You can feel there are actual engineers behind it, not just salespeople.
Bùi Thị Thanh NgọcVietnam · October 2025Solid phone validation API
We use 1Lookup inside our telemarketing app to verify numbers before they go to the dialer. Setup was simple and the results have been consistent. It's not overloaded with features, just fast, accurate, and reliable. Docs could be a bit deeper, but honestly, it works out of the box.
Dirk van MeerUnited States · December 2025Saved us from hundreds of spam signups
We run a SaaS product with free trials and were getting flooded with bots and fake users. After integrating 1Lookup, the difference was night and day. It quietly filters out junk signups without blocking legitimate customers. The support team even helped us fine-tune our risk thresholds on a quick Zoom call. Being honest, we couldn't ask for more.
Ido ShachamUnited States · January 2026A good addition to our workflow
1Lookup has been a good addition to our workflow over the last few months. We use it to verify IPs, emails, and phone numbers, which has noticeably cut down the time we spend chasing dead-end applications. It's reasonably priced and their support team is actually helpful. It's a very practical tool for what we need.

Bouncer (usebouncer) vs 1Lookup FAQ
Common questions about Bouncer (usebouncer) and switching to 1Lookup
What is Bouncer (usebouncer)?
Bouncer, found at usebouncer.com, is an email verification service that cleans mailing lists by flagging invalid, disposable, and risky addresses before you send. It offers bulk list validation, a real-time API, a deliverability toolkit, and integrations with common email and marketing platforms. Its focus is email hygiene rather than phone number or IP address data.
How much does Bouncer (usebouncer) cost?
Bouncer uses a pay-as-you-go, credit-based pricing model, and its purchased credits do not expire. As of publication, pricing starts around $8 for 1,000 email verifications, with the effective per-email price dropping as you buy larger volume packs. Bouncer also offers a free plan for a small number of emails so you can test it first; pricing can change, so check Bouncer’s pricing page for current figures.
What is the best Bouncer (usebouncer) alternative?
The best alternative depends on what you actually need to verify. If you only clean email lists, Bouncer is a capable, affordable choice; if you also need phone and IP validation, 1Lookup is a strong Bouncer alternative because it handles all three through one API and one universal credit balance. That consolidation lets teams verify emails, phone numbers, and IPs without stitching together separate vendors.
How is 1Lookup different from Bouncer (usebouncer)?
Bouncer specializes in email verification only, while 1Lookup validates phone numbers, emails, and IP addresses from a single API and one universal credit system. 1Lookup refreshes its data daily from FCC and carrier sources and returns a fraud score on every lookup, and it also offers carrier/HLR lookup, reverse lookup, and IP fraud intelligence. Both are strong at what they do; 1Lookup’s edge is unifying phone, email, and IP checks in one platform.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can test phone, email, and IP validation before committing. You can sign up and start validating right away without needing to contact sales first.
The Complete Bouncer Alternative
Why limit yourself to email-only validation? Move to 1Lookup for complete user validation on one plan.

The same month, priced both ways
Pick one of Bouncer’s own published volumes. Their figure is their published price at that tier; ours is the cheapest plan on our rate card that covers it. Nothing here is interpolated.
1Lookup
$99/mo
The Starter plan, 20,000 credits a month at $4.95 per 1,000. Using 10,000 of them is 50% of the plan, so $9.90 per 1,000 effective.
Bouncer
$60
Their published price for “10,000 credits”, at $6 per 1,000.
At 10,000 a month, Bouncer is $39 cheaper. Our smallest plan that covers this volume includes 20,000 credits, so the gap closes as you use more of it.
Bouncer rates as published on usebouncer.com, verified July 2026. Pricing models differ (a monthly plan is not a credit pack), so a like-for-like month depends on your real mix of lookups. Check their pricing page

Before you sign: Bouncer and 1Lookup on the operational terms
The terms that decide what a year actually costs, rather than what the first month does. A blank means we could not verify it on either product’s published pages, not that the answer is nothing.

Bouncer fine print worth reading twice
Published terms that change what Bouncer costs or what you can do with it. Each one links to the Bouncer page it was read on, because a claim about somebody else’s contract should be checkable in one click.
The Deliverability Kit (inbox placement tests, blocklist monitoring, SPF/DKIM/DMARC and SpamAssassin tests) is a separate monthly subscription starting at $25/month for 250 test emails and 10 IPs/domains, and is not covered by email verification credits.

What you actually work in
Bouncer is a app screenshots of the Deliverability Kit, including an inbox placement test results screen with an inbox/spam/unreceived/waiting donut chart and Back, Delete test and Open report buttons, plus blocklist monitoring and test set-up screens product you log into. 1Lookup is an API and a dashboard you mostly do not log into: you call it from the system that already has the record. Which of those you want is usually the whole decision, so here is theirs.
